Door Rust on 2006 GMC Sierra Pickup

[Qucet]

Hey guys,
I was wondering, if you guys in shops have noticed a lot of Chevy/GMC trucks in the 05-07 model years with rust already forming on the seam where the outer door skin is attached to the door. Especially the bottom. I was on a lot today and every one of the 6 trucks I looked at had some...or a lot.
I have my eye on one of the 06's, but this has me bummed a bit.
I was considering buying it, then wire wheeling the areas, epoxy priming and then having the lower 8 inches of the body Line-X'd (or some other brand) and having it wrap around to cover the seam leaving the drain holes open of course. Then have the inside of the door sprayed with fluid film or similar.
Do you think this idea would last a long time......like 5-10 years? I've come to a point where I think I want something newer than what I have to get away from paint/rust issues https://rustconverters.net/best-rust-removers/ . Just wondering if I should just steer clear of these trucks or if my "fix" really is a fix. I need to make a decision by tomorrow on this truck so advice is greatly appreciated....fast! LOL!

Depressing isn't it,I mean they are hitting 15 yrs. Old,but they price them like there's no rust,and there is everywhere,lurking,waiting for one more winter,your plan sounds good, Maybe have to do it twice

This is common with many vehicles from all makes. Make sure the drain holes are all clean. In the spring when you know it’ll be dry out for a few days, take a garden hose and flush out those holes. You’ll be surprised what you’ll see flow out. Keep flushing them until clean water runs out. Then take pressurized air and carefully blow the water out without blowing the paint off. Drive it around like normal for a couple of dry days. Then squirt in some CRC Marine Heavy Duty Corrosion Inhibitor so that it leaks out of the drain holes. Put cardboard under the doors so it catches the drippings. It’ll stink for a few days and then the odor will disappear.
Doing this annually and BEFORE the rust starts will ensure you won’t have any issues. The Canadians have been doing this for decades and their cars really don’t rust out like ours. It’s common to see an early 90’s sedan in showroom condition driving around in the winter time over there.

If it is already rusted then you need to grind the hell out of it until you see no more rust and fill it with fibreglass filler. To do it right you would replace the bottom metal or the whole door. I’ve hack and packed friends of mines to get the job done and to match their $$$ budget. The Raptor product is excellent and it is color matched too. Check out a couple trucks I did.
